Jar 557ml" act'description, reference beinghaid to the To all whom z't mag/concernfl v Be it known that 'I, JOSEPH ANDRAssY, a

citizen of theUnited States, residing at Cleveland, in the county of Cuyahoga' and State ofv Ohio,;have' invented a certain new. and useful Improvement in. Ventilators, of which thefollowing is a full, clear, and exaccompanying drawings,

' producing} forced draft so tliatincalmor "This invention relatesto ventilators more particularly to the type used on ships forventilation between and belowdecks and has for its object the provision of a ventila- I tor adapted vfor use ln stormyaorfheavy weather as Well as idealweather; f Anotheu object is. to provide 'means' for stormy weather a j more uniform ventilation is thereby secured. H r i 7 With these and other Objects :in-vie w,-the invention consists in the various novel features of construction and.v arrangement of parts shown in the, accompanyingdrawing Figure 1 is a front, elevationoff my device with the storm doors thrown open; Fig. 2

is a similar viewwith the storm doors closed; Fig. 3 is a sectional view on the line 33 of-Fig. 2, Fig; 4 is asectional 'vieWon the line 44 of Fig. 3 andFig, 5 is an enlarged sectional view of the mouth of the ventilator. v i

The ventilator consists the "usual up-g right stack 1 fitted at itsbase' with the re inforcing band2' so'that the stack can be from the deck (notl.show n); ,-The upper end,

i bead 81 ,ab out its periphery whichrispreferof the stack is provided With-a cowl 4 having its opening or mouth 5 fitted withia pair of storm doors 6. The doors 6' are preferably hinged to the sides ofthe cowl by hinge -members 7 so that when opened. the doors;

fold back and present a small'surf-aceandi consequently offer little resistance to the wind, asshown'in Fig.1.

The mouth of the cowl hast 'fi' ishingably rounded on its outersurface'hhdfleit tened on' the inner side,- so as'not to 'materially reduce the diameterof the c'owl mouth and thus interfere with 1 the supply of air to the ventilators when the doors are open',"the v bead being also flattened on its forward side so astopresent an abutment for the doors when closed. A lug 9,, carrying a bearing :10 is pr'eferably formed integral with the s c iiie ei igef' tt gl atenti: j t enteddwar ifi I: bead at the; lower edge of the mouth of the. i

cowl, the purpose of which will be fully dee. f

scribed later. V The doors 6 are. provided with openings 7 11 which are covered on the outer fa'ce of the doors by hoods 12 having'botto n open- 1 J ings' 13'; J he peripheryof the inner face oteach of the doorsfis provided with a rubber gasket 14' held in place by suitable,

fastenings such as the clips 15. 'A 'pairof latch 'members16 serveto holdthe doorsin the closed position; It-will bejnoted that I tl'ie'ed ges oflth'e doors overlap one another;

presenting asubstantially water-,tight fcov-" -ering the mouth of the cowl but atzthe 'g same itime allowing air, to bef,admitted' when closed, as .shown in Fig. 4; thereby;

through the, o

. ,A fan memberil? mounted Onasha ft-IS to the walllof the cowl. The fan may' be driven in 'any suitable manner from belowi as by a motor (not shown) connected to thepenings 13 and i 11 to the ,ven- 1 i Filator stackp Bis k'journaled atone 'end in thebearing- 10, i and at the otherend in a bearing 19 fastened fan shaft by a 'rbelt 20. Thus instormy" the'doors may be left open and the fan op erated to secure the desiredventilation weather,when thedoorsai'e closech a forced; draftfinay be securedyor in calm weather;

4 It will be'readily apparentthat-I have provided a ventilatorxwhich is equally elf ficient under allweather,conditions d j Q, pable of producing the desired ventilation at all times, Y j 167; aving husdescribed my invention,1what v 7 claim s:
